When I play in the free-rolls, I have learned to inderstand that most people who are all-in before the flop of the first hand are the ones not to worry about to much later on in the tourney. Depending on where the button lands on the first hand, I either limp in on the blind or fold and sit back and watch the table and get that valuable info that I would need later on in the tourney if someone is gettin lucky enough to win an all-in hand with a 2-7 offsuit and go all in and pull a miracle out of their buttox.
I tend to play suited hands and faces early on and allow the "all-iners" to wein themselves out of the tourney on their own.
As the tourney continues, I may play a weaker hand depending on the situtaion of the table. When you have 2000 people in a free-roll and 1900 of them are just there to be there just because it was free, they tend to play loosely and in my opinion do not learn alot from their playing.
I have noticed one thing in free-rolls I attend, I am either going to be among the first ones out after the yahoo's have donated all of their chips to the other players or I am in the top 50 remaining.
ITS ALL LUCK
Cheers
